Tips
• To enable this function, select set value 2 (BCD output) of Parameter Number 20 (Tolerance/BCD output
mode switching).
• It is possible to invert the data output logic by setting Parameter Number 21 (logic selection) to 1 (H).
• For details on the timing chart, see "5.5.4 Timing Chart" (page 52).
Analog output
Movement of the spindle of the gage head can be monitored as linear voltage by measuring the volt-
age between terminals with a pen recorder or oscilloscope.
Ach (upper display): Pin numbers 22–24
Bch (lower display): Pin numbers 23–24

5.5.3 Input Function
With an external signal input, you can switch the BANK, switch Peak mode, activate the Preset func-
tion, clear the peak value, set the memory, and clear the memory.You can also activate a HOLD on
the counter values of Ach (upper display) and Bch (lower display) either separately or simultaneously.
